Referring to fig. 1, fig. 1 is a schematic structural diagram of a blending assembly in an embodiment of the present application, and a first technical solution adopted in the present application provides a blending assembly, including: a barrel 10 and at least one propeller blade 12.

The cylinder 10 forms a receiving space, as shown in fig. 1. The inner wall 11 is formed on the cylinder 10, and the screw blade 12 is arranged in the accommodating space of the cylinder 10. The accommodating space of the cylinder 10 may be a cylindrical space, such as a cylindrical space, but a person skilled in the art may also set the accommodating space to have another shape, such as a square cylindrical space or a rectangular cylindrical space, which is selected according to the need, and is not limited herein.

At least one propeller blade 12 is positioned in the accommodating space and arranged on the inner wall 11 of the cylinder 10; that is, the connection surface of the propeller blade 12 may be disposed on the inner wall 11 of the cylinder 10 so that the connection surface of the propeller blade 12 is in close contact with the inner wall 11 of the cylinder 10. The shape of the connection face of propeller blade 12 is the same with the shape of inner wall 11 of barrel 10, all is the arc for example, and the connection face that also is propeller blade 12 is an cambered surface, and the shape of the inner wall 11 of barrel 10 also is a cambered surface, and two cambered surfaces conflict each other to possess common centre of a circle, so realize that propeller blade 12's connection face is hugged closely with the inner wall 11 of barrel 10.

Wherein, barrel 10 can be used for holding liquid, and for example liquid can be fluid reagent, and the height of barrel 10 needs to satisfy predetermined height, and propeller blade 12 can set up on barrel 10's inner wall 11 along direction of height AB.

Optionally, the propeller blade 12 is disposed above the bottom of the cylinder 10, i.e., the distance between the propeller blade 12 and the bottom of the cylinder 10 may be 1cm to 10cm, such as 1cm, 3cm, 5cm, 8cm, 10cm, and so on. Of course, the predetermined distance may also be set to be one tenth to one fourth of the height of the cylinder away from the bottom of the cylinder 10, such as one ninth, one eighth, one seventh, one sixth, one fifth, etc., and is set according to the requirement, which is not limited herein.

The number of the propeller blades 12 can be set by adjustment, for example, 1 propeller blade 12, 3 propeller blades 12, or other number of propeller blades 12 can be adopted, and the number is specifically set according to the need, which is not limited herein.

Specifically, the number of the propeller blades 12 may also be set according to the rotation speed of the cylinder 10, for example, if the rotation speed of the cylinder 10 is lower than a preset value, the number of the propeller blades 12 is appropriately increased, for example, 3 propeller blades 12, 4 propeller blades 12, and the like are adopted, and if the rotation speed of the cylinder 10 is higher than the preset value, the number of the propeller blades 12 is appropriately decreased, for example, 1 propeller blade 12, 2 propeller blades 12, and the like are adopted, and the setting is specifically performed as needed, which is not limited herein.

In the process that the blending assembly of this embodiment rotates with the cylinder 10 at a high speed, the liquid in the cylinder 10 flows along with the propeller blades 12, so that the liquid in the cylinder 10 is blended.

The propeller blade 12 at least includes a first inclined surface 121 and a second inclined surface 122 extending along the height direction AB of the cylinder 10, and when the mixing component rotates, the liquid in the cylinder 10 flows along the first inclined surface 121 and the second inclined surface 122, so as to mix the liquid.

Generally, if propeller blade 12 includes 2 inclined planes, if the contained angle between first inclined plane 121 and second inclined plane 122 and the barrel 10 bottom is 90 °, then form perpendicular paddle structure, in the process that perpendicular paddle blade drives the high-speed rotation of fluid reagent, fluid reagent can upwards climb from the centre of a circle position, however perpendicular paddle blade often hinders fluid reagent's crawling, thereby leads to fluid reagent's viscosity and only confines to a less space, and then leads to fluid reagent can't reach the mixing effect that needs.

Generally, the vertical structure of the paddle is used, the loading amount of the paddle is 40% -50% at most, and the stirring degree of uniform mixing is 90% at most. And through this application setting propeller blade 12 highly different, the loading of fluid reagent can reach more than 70% at most, and the stirring uniformity degree can reach more than 90%, so can obtain the advantage of propeller blade 12 of this application is greater than vertical paddle structure.

Alternatively, the propeller blade 12 includes a plurality of mutually connected inclined surfaces, such as a first inclined surface 121 and a second inclined surface 122 extending along the height direction AB of the cylinder 10, and a first inclined surface 121, a second inclined surface 122, a third inclined surface (not shown) and other inclined surfaces extending along the height direction AB of the cylinder 10, which can be selectively set according to the viscosity of the liquid and the rotation speed of the cylinder 10, and is not limited herein.

Therefore, the present application can provide a kneading assembly by providing the screw blade 12 with the first inclined surface 121 and the second inclined surface 122 extending in the height direction AB of the barrel 10. In the process that the propeller blade 12 drives the liquid to rotate at a high speed, the liquid flows along the first inclined surface 121 and the second inclined surface 122, and the first inclined surface 121 and the second inclined surface 122 make full use of the climbing effect of the fluid, so that the liquid can achieve the effect of uniform mixing.

Referring to fig. 2, fig. 2 is a schematic sectional view of the blending assembly in fig. 1, and further, an included angle between the first inclined surface 121 and the second inclined surface 122 is an acute angle. That is, a connection line is intersected between the first inclined plane 121 and the second inclined plane 122, and an included angle between an extension line which is positioned on the first inclined plane 121 and is perpendicular to the connection line and another extension line which is positioned on the second inclined plane 122 and is perpendicular to the connection line is an acute angle. Of course, the angle may be a right angle or an obtuse angle, and may be 0 degrees, but not 180 degrees. Of course, other angles, such as 30 °, 45 °, 60 °, etc., may be provided according to the requirement, and are not limited herein.

If the angle is 90 degrees, the first inclined surface 121 and the second inclined surface 122 are arranged perpendicular to each other, but at this time, a connecting line intersecting between the first inclined surface 121, the second inclined surface 122, and the first inclined surface 121 and the second inclined surface 122 cannot be perpendicular to the bottom of the cylinder 10 in the height direction AB of the cylinder 10, so that the propeller blades 12 form a vertical blade structure, and the vertical blade often hinders the creeping of the fluid reagent, which results in that the fluid reagent cannot achieve a desired uniform mixing effect.

In addition, in order to prevent the first inclined surface 121 and the second inclined surface 122 from being perpendicular to the bottom surface of the cylinder 10, the first inclined surface 121 and the second inclined surface 122 extending along the height direction AB of the cylinder 10 form an included angle with the bottom surface of the cylinder 10, and in order to maintain a better blending effect, the included angle may be an acute angle, such as 30 °, 45 °, 60 ° and the like, and is specifically set as required, and is not limited herein.

Certainly, the included angle between the first inclined surface 121 and the bottom surface of the cylinder 10 and the included angle between the second inclined surface 122 and the bottom surface of the cylinder 10 may be the same or different, and generally, in order to better mix the mixture, the included angle between the first inclined surface 121 and the bottom surface of the cylinder 10 and the included angle between the second inclined surface 122 and the bottom surface of the cylinder 10 are generally set to be different, for example, the included angle between the first inclined surface 121 and the bottom surface of the cylinder 10 is 60 °, the included angle between the second inclined surface 122 and the bottom surface of the cylinder 10 is 30 °, and the setting is specifically performed according to needs, and the limitation is not performed here.

When the included angle between the first inclined plane 121 and the bottom surface of the cylinder 10 and the included angle between the second inclined plane 122 and the bottom surface of the cylinder 10 are different, when the blending component rotates, the flowing speed of the liquid in the cylinder 10 along the first inclined plane 121 and the second inclined plane 122 is also different, so that the fluids on the two inclined planes can be stirred to different degrees, and the fluids on the two inclined planes form a fast and slow flowing state, so that the liquid can reach the blending effect.

Further, referring to fig. 3, fig. 3 is a schematic top view of the blending assembly of fig. 1. Because the barrel 10 needs to hold liquid, such as fluid reagent, because the barrel 10 has certain height in direction of height AB, so propeller blade 12 can set up apart from barrel 10 bottom predetermined distance on the inner wall 11 of barrel 10 in direction of height AB, for example keep away from barrel 10 bottom 1cm ~10cm, for example 1cm, 2cm, 3cm and 4cm etc.. Of course, the predetermined distance may also be set to be one tenth to one fourth of the height of the cylinder away from the bottom of the cylinder 10, such as one ninth, one eighth, one seventh, one sixth, one fifth, etc., and is set according to the requirement, which is not limited herein.

Of course, for more fluid loading and better blending effect, the propeller blades 12 may be disposed on the bottom surface of the cylinder 10, so that the fluid flows on the inclined surfaces of the propeller blades 12 sufficiently, so as to achieve the effect of blending the liquid.

Wherein, the mixing subassembly includes a plurality of propeller blades, and a plurality of propeller blades can be in the staggered arrangement in direction of height AB, for example propeller blade 12, propeller blade 13 and propeller blade 14 to for example propeller blade 12 can set up in the position of 1cm bottom the barrel 10, and propeller blade 13 can set up in the position of 3cm bottom the barrel 10, and propeller blade 14 can set up in the position of 2cm bottom the barrel 10, specifically sets up as required, does not do not restrict here.

The plurality of screw blades are arranged along the circumferential direction of the cylinder 10, and the orientation of the plurality of screw blades is the same, specifically, for example, the intersection line of the first inclined surface 121 and the second inclined surface 122 on the screw blade 12 is L1, the intersection line of the two inclined surfaces of the screw blade 13 is L2, and the intersection line of the two inclined surfaces of the screw blade 14 is L3, then the orientation of the intersection line L1 of the screw blade 12, the intersection line L2 of the screw blade 13, and the intersection line L3 of the screw blade 14 is the same, for example, arranged clockwise or counterclockwise in the circumferential direction of the cylinder 10, so that the orientation of the plurality of screw blades is the same.

In addition, a connection line L1 intersecting between the first inclined surface 121 and the second inclined surface 122, an intersection line L2 of the two inclined surfaces of the propeller blade 13, and an intersection line L3 of the two inclined surfaces of the propeller blade 13 may be a straight line, as shown in fig. 3, or may be a curved line, which is not limited herein.

Furthermore, in order to make the cylinder 10 lighter and save material, the propeller blades 12 may be hollow, i.e. several faces of the propeller blades 12 enclose a closed tetrahedron, and the connecting face connecting the inner wall 11 of the cylinder 10 is an arc face which is the same as the center of the circle of the inner wall 11 of the cylinder 10 and the shape of the inner wall 11, so that the propeller blades 12 are tightly fixed on the inner wall 11 of the cylinder 10.

Further, the ratio of the height of the propeller blades 12 to the height of the cylinder 10 may be one third to three quarters, such as one third, one half and three quarters, specifically, the height of the plurality of propeller blades may be consistent with the height of the cylinder 10, and of course, the ratio of the height of the plurality of propeller blades to the height of the cylinder 10 may not be consistent.

For example, when the fluid is subdivided into different layers, the ratio of the height of the plurality of propeller blades to the height of the cylinder 10 is not uniform, so that the fluid in the cylinder 10 is uniformly mixed at different layers, of course, the plurality of propeller blades enclosing a closed tetrahedron may have the same volume or different volumes, and are specifically set according to needs, which is not limited herein.
